APPARATUS FOR FORMING TYPE UNDER PRESSURE.

SEECIFIQATION forming part of Letters Patent No. 745,208, dated November 24, 1903.

Application filed March 2, 1903. Serial No. 145,860. (No model.)

To all whom it may concern:

Be it known that we, GEORGE G. LITTLE and EDWIN A. REED, citizens of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Apparatus for Forming Type Under Pressure, of which the following is a specification containing a full, clear, and eX- act description, reference being bad to the ac.- companying drawings, forming a part hereof.

Our invention relates to improvements in apparatus for forming type under pressure, and has for its object to provide means whereby the metal from which the type is made may be subjected to uniform pressure upon all of its sides during the operation of producing the type, so that the type when mad shall be perfectly symmetrical.

In the drawings, Figure 1 is a transverse vertical mid-section of a device embodying our invention, showing the longitudinal dies in place within the jaws, whereby pressure is imparted to them. Fig. 2 is a perspective showing all of the longitudinal dies in position with the face-forming die in place. Fig. 3 is a perspective showing the four longitudinal dies employed in the device of our invention. Fig. 4. is a side view showing all of the dies in place. Fig. 5 is a vertical midsection of our device, taken along the line 5 5 of Fig. 4. Fig. 6 is a vertical longitudinal section of the same, taken along the line 6 6 of Fig. 5. Fig. 7 is a perspective of the faceforming die, such as was used in our apparatus. Fig. 8 is a perspective of a completelyformed type made by the use of our apparatus.

In detail our apparatus may be described as follows: We provide fou-r longitudinal blocks a b c d of equal size. These blocks are placed in position as follows: The blocks ctand b are superimposed, as shown in Fig. 2. The blocks 0 d are then placed in position, as shown in Fig. 3. There is thus formed the opening 01, which is shown in transverse section in Figs. 1 and 5 and in longitudinal section in Fig. 6.

The blocks a b 0 cl are of such width in relation to their thickness that when the opening (1 has thus been provided the mass formed by the longitudinal blocks is square in transverse section, as shown in Figs. 1 and 5. The

block'from which the type is to be formed having been inserted in the opening (1, the face forming die e is placed in position against one end of the opening cl, as shown in Figs. 4 and 6. Each of said face-forming dies may be adapted to form four letters, as indicated by Fig. 7. The end block fcorresponds in its dimensions to the face-forming die e and is placed in position against the op posite end of the opening 01, as shown in section in Fig. 6. The blocks a b c d, face-forming die e, and end blockf being thus assembled in contact with the metal which is to be shaped into a type, pressure is administered to the outer surfaces of all the blocks (a, b, c, d, and f) to a degree which is sufficient to hold them rigidly in place to produce a type perfectly symmetrical and the body of which is perfectly rectangular, as shown by the type g in Fig. 8, while the face-forming die 6 is forced against the end of the type. Such pressure may be administered in any-of the methods known to the art. In Fig. l we have indicated the blocks a b 0 cl as being in place within vise-jaws h and i, the vise-jaws h and 2' being provided with the rectangular depressions j to receive and hold the blocks ab 0 d in place.

Having thus described our invention, what we claim as new, and desire to have secured to usby the grant of Letters Patent, is-

An apparatus of the class named consisting of four longitudinal blocks adapted to be placed in contactto form an opening for the metal to be operated upon, a face-forming die adapted to fit into the blocks and over oueend of the opening to form the face of the type, and an end block adapted to close the opposite end of the opening, all of the said blocks and dies being adapted to communicate pressure to an inclosed piece of
